Please, pass me a wing, Calvin. No! You can't have any! It's mine! All mine! The late cretaceous...when the world meant business. A gigantic quetzncoatlus, a pterosaur the size of an airplane swoops over the horrible tyrannosaurus! The tyrannosaur lunges and brings down the flying pest! Uh oh! The commotion attracts other tyrannosaurs, greedy for an undeserved piece! Driven away by the fierce roaring and gnashing of the intruders, the tyrannosaur nurses a deep grudge. Revenge will soon be his!
